scope:

This information sheet covers a method for the evaluation of load distribution across the teeth of parallel axis gears. A general discussion of the design and manufacturing factors which influence load distribution is included.

The load distribution factors for use in AGMAparallel axis gear rating standards are defined, to improve communication between users of those standards.

Historically, analytical methods for evaluating load distribution in both AGMA and ISO standards have been limited by the assumption that load is linearly distributed across the face width of themeshing gear set. The result of this assumption is often overly conservative (high) values of load distribution fac- tors. The method given here is considered more correct.
